The people I interviewed with were all very welcoming. No one seemed to have a "prove why we should even consider you" attitude as some interviewers do. However, the process was a bit chaotic as more people and more interviews were added as it went along.

Lengthy with a lot of rescheduling. Ended up diminishing my impression of the company a bit. Experience confirmed the negative feedback here on HR. Hiring manager was minimally involved and other interviewers were pretty distracted. Most of the interview seemed to be mining me for info on competitors.
